Technical Field

[0001] The present invention relates to the technical field of metal cutting equipment, and in particular to a cutting equipment for bearing metal raw materials. Background Art

[0002] In the process of bearing manufacturing, the raw materials are all columnar metal blocks. When manufacturing the outer ring and inner ring of the bearing, the columnar raw materials need to be cut into round blocks. After calcination, they are forged into small round blocks. After calcination, they are extruded into rings through equipment and then polished to form a complete shaft ring.

[0003] Generally, metal raw materials are cut by a saw or a circular sheet cutting equipment. The cutting methods are all cutting methods in a straight line direction. The cutting method of the saw is a reciprocating motion for cutting. Since the saw teeth on the saw are skewed to one side, there will be one motion that belongs to reset during the reciprocating motion. And the depth that the cutting circular sheet on the circular sheet cutting equipment can penetrate is only close to the diameter distance of the circular sheet, and the cutting of the circular sheet requires continuous adjustment of the position of the raw material or an increase in the diameter of the cutting circular sheet to complete the complete cutting. Therefore, it is inconvenient to cut the raw material and the cutting efficiency of the raw material is affected at the same time. Summary of the Invention

[0022] Embodiment

[0023] Please refer to Figure 1 - Figure 2 , the present invention provides a cutting device for bearing metal raw materials, including a workbench 1 and a bracket 2. A plurality of support rollers 4 for placing columnar metal blocks 3 are installed on the workbench 1, and a driving member 5 for driving the support rollers 4 to rotate is installed on the workbench 1. The bracket 2 is installed on the workbench 1. A plurality of clamping mechanisms are installed between the workbench 1 and the bracket 2. The clamping mechanisms cooperate with the support rollers 4 to clamp the columnar metal blocks 3 and drive the columnar metal blocks 3 to rotate on the workbench 1 through the support rollers 4. An arc-shaped hacksaw 6 is rotatably installed on the bracket 2. A first driving mechanism 7 is connected between the arc-shaped hacksaw 6 and the bracket 2, and the first driving mechanism 7 can drive the arc-shaped hacksaw 6 to approach the columnar metal block 3. In the present invention, the columnar metal blocks 3 are placed on the support rollers 4. The arc-shaped hacksaw 6 is pushed by the first driving mechanism 7 to fit the surface of the columnar metal blocks 3. The clamping mechanisms keep the columnar metal blocks 3 on the support rollers 4 all the time. The driving member 5 drives the columnar metal blocks 3 to rotate, so as to achieve the cutting effect.

[0024] In a specific embodiment, referring to Figure 1 and Figure 2 , the clamping mechanism includes a chain-shaped clamping chain 81 and a second driving mechanism 82. Two second driving mechanisms 82 are respectively rotatably installed on both sides of the bracket 2 to form a set of clamping mechanisms. One end of the clamping chain 81 is rotatably installed on the second driving mechanism 82, and the other end is rotatably installed on the workbench 1. The second driving mechanism 82 can drive one side of the clamping chain 81 to fit against the surface of the columnar metal block 3. Each set of second driving mechanisms 82 clamps one toroidal surface of the columnar metal block 3. The clamping chain 81 is in a movable state. Under the action of the second driving mechanism 82, the clamping chain 81 is made to fit against the columnar metal block 3. The clamping chains 81 on both sides form a set, avoiding the situation where the columnar clamping block is not tightly clamped due to unilateral clamping. At the same time, there are multiple sets of clamping chains 81 in the device, further achieving the effect of clamping. In the present invention, a single clamping chain 81 and the connected second driving mechanism 82 are located on the same side of the columnar clamping block, facilitating the placement of the columnar metal clamping block.

[0025] In a specific embodiment, referring to Figure 1 and Figure 2 , the clamping chain 81 includes a connecting frame 811 and rollers 812. A plurality of rollers 812 are sequentially and spacedly connected by a plurality of connecting frames 811 to form the clamping chain 81. The rollers 812 of the clamping chain 81 fit against the surface of the columnar metal block 3. The clamping chain 81 achieves a movable effect through the connecting frame 811 and the rollers 812. The rollers 812 on the clamping chain 81 can cooperate with the support rollers 4 to enable the columnar metal block 3 to rotate when being clamped.

[0026] In a specific embodiment, referring to Figure 1 and Figure 2 , a central bracket 21 is installed at the upper end of the bracket 2. Two first driving mechanisms 7 are rotatably installed on both sides of the central bracket 21. Both ends of the arc-shaped hacksaw 6 are respectively rotatably installed at the end of the central bracket 21 and the first driving mechanism 7. The first driving mechanism 7 can push the arc-shaped hacksaw 6 towards the columnar metal block 3.

[0027] In a specific embodiment, referring to Figure 1 and Figure 2 , both ends of the arc-shaped hacksaw 6 are bent away from the columnar metal block 3. In the present invention, two arc-shaped hacksaws 6 are used, and the two arc-shaped hacksaws 6 are in the same vertical plane, ensuring that the cut grooves match. At the same time, the bending of the arc-shaped hacksaw 6 can ensure that when the two arc-shaped hacksaws 6 approach each other, they contact at one point, avoiding damage caused when the arc-shaped hacksaws 6 approach each other.

[0028] In a specific embodiment, referring to Figure 1 and Figure 2, the workbench 1 is hollowly arranged. A plurality of through grooves 11 are formed in the upper table board of the workbench 1. A plurality of lifting rollers 12 are installed in the workbench 1. The lifting rollers 12 can pass through the through grooves 11 to the upper surface of the workbench 1 and support the columnar metal block 3. The lifting rollers 12 move the columnar metal block 3 in the direction of the axis line to prepare for the next cutting effect.

[0029] In a specific embodiment, refer to Figure 1 , Figure 2 , the rotation axis of the roller 812, the rotation axis of the clamping chain 81 relative to the workbench 1, the rotation axis of the support roller 4, and the rotation axis of the arc-shaped saw 6 relative to the workbench 1 are parallel to the axis line of the columnar metal block 3. Ensure that the columnar metal block 3 can rotate under clamping.

[0030] In a specific embodiment, refer to Figure 1 , Figure 2 , the lifting roller 12 includes a lifting table 121 and a driving roller 122. The driving roller 122 is rotatably installed on the lifting table 121, and the rotation axis of the driving roller 122 is perpendicular to the rotation axis of the support roller 4. The lifting height of the lifting table 121 is the sum of the heights of the workbench 1 and the support roller 4. When the cutting is completed, the clamping chain 81 and the arc-shaped saw 6 are separated from the surface of the columnar metal block 3. After the lifting table 121 is raised, the columnar metal block 3 is slightly lifted, and the columnar metal is driven to move in the direction close to the arc-shaped saw 6 by rotating the driving roller 122. When in a suitable position, the lifting table 121 descends, and the columnar metal block 3 is placed on the support roller 4, repeating the entire cutting process.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
